Bubbers, Not up to your usual professional standards to publish something like that "article" of unknown pedigree.
For those wondering about the effects of "heating" the air, inside the pitot tube, remember that it should not be trapped if we can keep the tube from getting plugged in the first place, and is always flowing through the tube to the drain ports at a relatively low speed. There is no way to change the pressure in the tube then from heating the gas inside the tube. (I suppose if you got really ridiculous with heating you could start looking at ramjet theory
). The idea is to be able to rapidly apply energy to the internal volume of the pitot tube, and if the thing begins to fill with solid water, to rapidly convert said solid water to a liquid so that it may be purged from the probe vent holes with dispatch. To do this reliably requires sensing systems and a better means of applying energy than is presently being used.
The absorption of either infrared energy or microwave energy by the atmosphere is miniscule unless you then throw in water in some form or other. There are some relatively narrow absorption bands in the infrared spectrum from molecular dynamics.
